LEATHER-DRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,669, dated December14, 1897.

Application filed May l2, 1896. Serial No. 591,208. (No model.)

To all whom it may concern.: A

Be it known that I, SAGER CHADWICK, of Philadelphia, in the State ofPennsylvania, have invented a certain new and useful Leather-DressingMachine, whereof the following is a specification, reference being hadto the accompanying drawings.

The object of my invention is to provide an apparatus for the mechanicaldressing of leather, including the application of oil or other materialto the skin.

In the accompanying drawings, Figure l represents a side elevation ofthe apparatus. Fig. 2 is a lon gitudinalvertical section through thesame. Fig. 3 is apartial section on a plane Similar to that of Fig. 2,but showing certain of the parts in different positions. Fig. 4 is a topor plan View of the apparatus, and Fig. 5 is a view of thedressing-roller.

The housings of the machine are represented at A and preferably consistof an open framework substantially of the character indicated. Extendingtransversely across the interior of the framework is a horizontal troughB to contain oil or other material which is to be applied to the skin. Aroller C, mounted upon the shaft c, is adapted to rotate within saidtrough, the shaft extending through the ends thereof and being providedat one end with a driving-pulley C2, actuated by means of a belt C3.Immediately above said roller is a second roller C', whose shaft c issupported in adjustable journal-boxes c2, which may be of any well-knownconstruction and capable of adjustment by means of a setscrew c3, so asto bring the surface of the roller C into more or less intimate contactwiththat of the roller C. This roller C is driven by frictional contactwith the roller C and is adapted to take up oil or other materialsupplied by the latter and feed it to the dressingroller D. Saiddressing-roller consists of a cylinder mounted upona shaft D and havingarranged longitudinally along its periphery projecting strips d,preferably of felt or other comparatively firm material, capable by itstexture or by the mode of its disposition of taking up the dressing.Each of these strips extends in a V-shaped or waved line, as indicatedin Fig. 5, and the exterior surfaces thereof rotate successively intocontact with the surface of the feeding-roller C,so as to take the oilor other dressing material therefrom. The dressing-roller D ispositively driven by means of a pulley D2 and belt D3.

Adjacent to the dressing -roller are two smaller rollers E E', (which Iterm the carrying rollers,) which are supported upon yokes F F upontransverse studs f, so that said rollers E E can rock or play freelyabout the studs f. Said studs f are mounted upon a shifting frame G ofbell-crank form, which is pvoted to the housings at G. Links H H arepivotally connected at g to the frame G and extend down to the treadleI, pivoted at i to the housings and provided with a footboard .I andsprings K Kf, which latter normally tend 'to-,hold the treadle, andconsequently the frame G, in its extreme upward position. (Indicated inFig. 2.) The motion of the frame throws the carrying-rollers E E ltowardor away from the dressing-roller D, the extreme position of said rollersbeing indicated, respectively, in Figs. 2 and 3. When in their outermostposition, (indicated in Fig. 3,) said carrying-rollers E E' are infrictional contact with a pair of disks L L', rigidly secured to a shaftZ, which is provided at one end with a sprocket-wheel P, having a chainn engaging with a driving sprocketpinion N, mounted upon the end of theshaft D of the dressing-roller D, so that the said disks are positivelydriven thereby. Upon the other end of the shaft Z is a sprocketwheel M,whose chain M' engages with a sprocket-pinion m, mounted upon a shaft t,which carries a beater R, having radiallyprojecting strips r, saidbeater being arranged a short distance below the dressing-roller D. Theseveral rollers are inclosed within a large tank B', which extendsbetween the housings and which serves to catch the drippings from therollers and skins, said tank being provided with an outlet B3 at thebottom to draw off the accumulations. A hinged cover B2 also extendspartially over the top of the machine to prevent the oil or othermaterial from being flung o upward. Atable A for skins may beconveniently arranged across one end of the apparatus and aledge orfeeding-board a at-the opposite end.

The operation of the apparatus is as fol- ICO lows: The tank B beingsupplied with oil or other dressing material, (indicated by 1),) theroller C rotates therein and supplies said material to thefeeding-roller C', also positively rotating the latter to supply thesame to the surfaces of the strips d upon the dressingroller. The amountof material thus supplied can be regulated by the pressure of thefeeding-roller upon the roller C. The operator, standing at theright-hand end of the frame in Figs. l and 2, draws the skin from thetable A', and then depressing the treadle I throws the carrying-rollersEE into their eX- treme outward position, thus bringing them intofrictional contact with the disks L L', so that they are rotated therebyin the direction proper to carry a skin S down into the apparatus. Theoperator, holding the skin, allows it to be thus carried down until itis properly within the grasp of said rollers, when he releases thetreadle, and the bell-crank G is then thrown upward and brings thecarryingrollers E E into their extreme inward position. (Indicated inFig. 2.) The skin S is then between the carrying-rollers E E' and thedressing-roller D and in frictional contact therewith. The rotation ofthe dressingroller D carries the skin downward (the operator stillholding the same and usu ally pulling backward upon it to obtain a moreVigorous action) and rubs or wipes the dressing material into it. Thestrips r of the beater prevent the lower end of the skin, however, frombeing carried around and becoming entangled with the strips d, and whenthe operator has thus fed the skin in as far as may be done withoutreleasing the same he pulls it out wholly or partially and repeats thisoperation as often as may be necessary. Then entirely withdrawing theskin, he inserts the other end thereof in a similar manner and dressesthe portion which `has previously been withheld from the action of therollers. The skin is thus subjected to a very thorough dressing, theV-shaped arrangement of the strips and play of the carrying-rollers E Epermitting a very effective kneading or working of the dressing materialinto the skin.

Having thus described my invention, I wish it to be understood that I donot limit myself to the precise mechanical details of the several partswhich are set forth in the above description of a preferred embodimentof my invention; but

I claiml. Thecombination, with a frame, a dressing-roller, and a rolleren gagin g the dressingroller and supplying the dressing materialthereto, of a feed or carrying roller movable toward and from thedressing-roller and means for rotating the feed or carrying roller whenmoved away from the dressing-roller, substantially as described.

2. The combination, with a frame, an oil or dressing receptacle thereon,a roller journaled in said receptacle, and a second roller contactingwith the first roller, of a dressingroller contacting with the saidsecond roller and supplied therefrom with dressing, and a pair of feedor carrying rollers movable toward the dressing-roller to hold the skinthereto and movable away therefrom to permit the entrance of a skin,substantially as described.

3. The combination of a dressing-roller; means substantially as setforth for supplying dressing material thereto; a pair of freelymountedcarrying-rollers arranged adjacent to said dressing-roller; a shiftingframe supporting said carrying-rollers; and actuating mechanism (asdisks, L, L',) arranged with relation to the extreme outward position ofsaid carrying-rollers, substantially as set forth.

It. The combination, with a frame, and a dressing-roller, of a pair ofcarrying-rollers to hold the skin to the dressing-roller, bell-cranklevers pivoted to the frame and to which the yokes or arms carrying thefeed or carrying rolls are pivoted and a treadle mechanism connectedwith said bell-cranks to move the feed or carrying rollers toward andfrom the dressing-roller, substantially as described.

5. The combination with a dressing-roller and means for rotating it, ofa normally-adjacent carrying-roller free to rotate in either directionto permit the operator to pull the skin outwardly for successive actionsby said dressing-roller, a driving means beyond and at that side of thecarrying-roller opposite the dressing-roller, and means for moving saidcarrying-roller away from the dressing-roller and into contact or meshwith said driving means whereby the said carrying-roller will thenbecome a positively-driven roll to feed t-he skin inwardly into positionfor action by the dressing-roller,substantially as described.

G. A leather-dressing machine, comprising a frame, a dressing-roller,dressing contacting supply-rollers, one of which engages thedressing-roller and the other of which enters a dressing-receptacle,feed or carrying rollers movable toward and from the forward side of thedressing-roller, means f for rotating the feed or carrying rollers whenmoved outwardly, and a beater rotating beneath the dressing-roller,substantially as described.

7. A leather-dressing machine, comprising the frame, a dressingroller, adressingtrough, rollers for conveying the dressing from the trough tothe dressing-roller, feed or carrying rollersin front of thedressing-roller to hold the skin thereto, means for moving the feed orcarrying rollers toward and from the dressing-roller, a drive-shaft inthe outward path of the feed-rollers to rotate the same when moved awayfrom the dressing-roller, a beater under the dressing-roller and thelarge inclosing tank, substantially as set forth.
